One of the last poignant questions from our previous Ryzen APU coverage is the way that integrated graphics scales with overclocking. As these low-end Ryzen APUs are all about gaming on a budget, our previous looks into core frequency and memory scaling lead naturally into examining how well the graphics overclocks and what extra performance can be had with a light touch of BIOS settings. We pushed both of our APUs to 1600 MHz on the graphics, representing a +45% overclock, which translates into some interesting results.

Ryzen 2000 Series APUs: Going For Gaming

The pairing of AMD's high-performance Zen compute cores and Vega graphics into a tidy little package was a resuscitation for integrated graphics, making the low-end desktop market a lot more interesting, as our Ryzen 5 2400G and Ryzen 3 2200G review concluded. In order to increase performance for gaming, there were three potential avenues to look into. The first one led to our analysis into how memory frequency scales with AMD’s APUs, based on the relationship between memory performance and gaming, showed that memory can have a positive impact on performance. The second was our Ryzen 5 2400G and Ryzen 3 2200G core frequency scaling article, which showed that increasing the CPU core speed didn’t have the effect on gaming performance one would potentially hope to find. The last of the set is overclocking the integrated graphics frequency, which often leads to a direct increase in frame rates.

The interesting thing to take from our Ryzen 2000 series APU overclocking guide was that the performance increase was easy to spot when every component on the amalgamated Zen and Vega package plus memory was pushed. The biggest take from our Ryzen APU memory scaling was that the Infinity Fabric interconnect did improve performance from memory in gaming, more so than pure CPU core frequency in certain cases. It was also noted that overclocking everything at once was more difficult than increasing each part independently - what was a good individual overclock, was not always possible when the CPU, memory, and graphics were overclocked together.

Focusing specifically on the intergrated graphics for this article, the primary aim is to ascertain whether or not overclocking the Vega cores on their own yields a big enough benefit in our game testing suite to make it worthwhile. As long as the graphics can continually be fed from the memory and infinity fabric, we should see a good linear increase, especially when the GPU is the bottleneck, however the resolutions aimed at these GPUs might throw interesting features into the mix.

In this review we will recover overclocking the integrated graphics, and take each APU from its stock graphics frequency up to the highest overclock we could achieve, in 50 MHz steps. The results, are interesting.

Test Bed and Hardware

As per our testing policy, we take a premium category motherboard suitable for the socket and equip the system with a suitable amount of memory. With this test setup, we are using the BIOS to set the integrated graphics frequency using the provided straps on the MSI B350I Pro AC motherboard. The memory is set to the maximum supported official speed. The CPU core frequency on both the Ryzen 5 2400G and Ryzen 3 2200G was left at their respective default settings.

We took our previous gaming suite for this comparison. It's a little dated, but it still checks out. We will be using newer games in future analysis pieces.

AMD's APU Stack

Since our last big coverage of AMD's Ryzen APUs, it was announced that several new parts will be coming to the market under the 'Athlon' brand. These will be much cheaper parts, starting at $55, and offering fewer cores and fewer Vega compute units for that market.

We currently have the 200GE in for a future review, but everything in this article should apply to this APU as well.

    Sorry to be a dick Gavin, but...

    oignant
    ˈpɔɪnjənt/Submit
    adjective
    evoking a keen sense of sadness or regret.
    "a poignant reminder of the passing of time"
    synonyms: touching, moving, sad, saddening, affecting, pitiful, piteous, pitiable, pathetic, sorrowful, mournful, tearful, wretched, miserable, bitter, painful, distressing, disturbing, heart-rending, heartbreaking, tear-jerking, plaintive, upsetting, tragic
    "the father of the murder victim bade a poignant farewell to his son"

    Its a sore point. I misused it similarly in a speech.

    Good effort, but a shame temps not included.

    There is a suspicious pattern here.

    On the 2400g at voltage bumped, 1600 gpu clock, it gets good results ... mostly. Its min frames are erratic and even lowered at times.

    This could well be heat.

    My take home, is that the Apu is so cool, its worth decent cooling and a low latency nvme system disk with a direct pci link to the cpu.

    The apu seems a hit in the linux world, and that the apu is becoming a kind of default zen/vega platform - a target for some intimate apu driver tweaking.

    Its fine wine indeed.

    I am having trouble finding it, but was the memory overclocked as well or just the iGPU? Reply

    I was reluctant to buy any new graphics card because of the sick prices, so I'm keeping my (really) old Radeon HD 6790(-ish GPU, can't remember exactly - GPU-Z states it has Barts core and 1 GB DDR5, clocked at 900/1100 MHz, respectively). And it's paired with Ryzen 5 1600, on Asus Prime B350-Plus board. Do you think switching CPU to Ryzen 2400G would be some upgrade in the GPU area? I'd like to return to WoW and also play some newer, but not demanding titles. (Slightly slower CPU won't be much of an issue for me). Reply

    It would be better for you to start looking for a new GPU- prices are getting good. RX570 for $150 would solve your problem better than switching to a 2400G. Reply

    Just buy a used card, or a GT1030/1050.

    They're available for roughly what the 2400G costs, but will give you a much bigger GPU boost.

    OP. u misuse poignant in ur opening. It has a "sad" connotation. Reply

    Heresy, given the curiously zealous loyalty folks have to sata ssd over clearly very superior nvme, but it would not surprise me if the HDD era SATA interface & even greater lag of the chipset the SATA ports run off, added some significant random delays by gaming standards.

    There is no comparison in; iops, processing overhead and access times.

    I am sure I have seen reviews where they don't even state the test rig's SSD details.
